TIMING
Turn-on delay is defined as the delta between the time that V
reaches >1.2 V and when V

The rise time is defined as the delta between the time from
10% to 90% of V
the RC time constant where C = load capacitance (C
R = RDS
an adequate approximation for RC is RDS
or load capacitor is not needed for the ADP198; however, capacitors
can be used to suppress noise on the board. If significant load
capacitance is connected, inrush current may be a concern.
Figure 27 through Figure 30 show the turn-on delay and output
rise time for each of the four settings on SEL0 and SEL1.
